I am having the deck of my boat refinished and decided to ditch the ancient genoa tracks and cars. The boat is 40ft Ctr Cockpit and uses up to a 150% Genoa, and I'm looking for advice on the type of system to use. It currently is set up with 2 cars in tandem on each track but I've never quite understood or took advantage of more than one. We do mostly laid back weekend/week cruising, not racing, so I'm looking for something workable that won't cost a fortune. I'm already spending way too much on the deck work, but it would be crazy not to replace some old hardware at this time. I was thinking of Harken..., What are the pros/cons of pinstop over slider, one or 2 cars, etc; Any advice, ? Thanks, Steve
